A coolant interface includes a line replaceable unit (LRU) inserted into a slot within a modular assembly such as a chassis for an electronics assembly. Quick disconnect fluid coupling fittings on the LRU mate with counterpart fittings on a fluid distribution manifold within the chassis when the LRU is inserted into the slot. A seal surrounding the quick disconnect fluid coupling fittings on a flat surface abutting a counterpart surface on the fluid distribution manifold when the LRU is inserted into the slot compresses the seal against the counterpart surface.

The invention relates to a method for regulating the maximum speed of a working machine (12), in particular an air compressor in a vehicle. Said working machine is driven by means of a motor (10), using a hydrodynamic coupling (11), which comprises a working chamber (3) that is partially or fully filled with a working medium for transmitting a torque from a drive side (11.1) equipped with an impeller (1) to a driven side (11.2) equipped with a turbine wheel (2). The method comprises the following steps: the speed of the working machine, of the driven side of the hydrodynamic coupling, of the drive side of the hydrodynamic coupling and / or of the motor is detected; a maximum permissible value for the speed is defined and compared to the detected speed; if the detected speed exceeds the maximum permissible value, the quantity of working medium in the working chamber of the hydrodynamic coupling is automatically reduced by the opening or passage of medium through an outlet that is connected to the working chamber.

The invention relates to a hydrophone housing. The housing comprises an outer casing with an exterior shape being in close contact with sediment when buried therein and having a deflectable wall part. Solid material partly fills the casing to define an outer chamber behind the deflectable wall part, a cavity shaped so that an inner chamber is defined immediately surrounding a hydrophone sensing element held therein, and a first duct for liquid flow communication between the outer chamber and the cavity or an internal volume of the hydrophone sensing element. Thereby, a hydraulic coupling is provided so that an acoustic pressure causing small radial displacements of outer surface of the housing will, via liquid in the first duct, cause large radial displacements of the hydrophone sensitive element. The area of the deflectable wall part is much larger than the area of the sensitive element so that only small displacements of the housing are required to cause large displacements at the hydrophone sensing element.

The invention relates to a water supply control method of a hot continuous rolling line ultra fast cooling system and belongs to the technical field of hot-rolled strip steel rolling. The water supply control method includes the following steps that: step one: the opening degree of a hydraulic coupler, namely, the flow curve of a pump station, is calibrated; step two: whether a strip steel head portion achieves a speed rise point is judged, if the strip steel head portion achieves the speed rise point, a rolling line transmits set pressure and total flow to the pump station, and step three is executed, otherwise, the step two is executed; step three: whether the set pressure and the set total flow which are transmitted to the pump station by the rolling line satisfy a set range is judged, if the set pressure and the set total flow satisfy the set range, an ultra fast cooling header is opened, and flow open-loop control and speed increase are performed on the pump station, and step four is executed, otherwise, alarming is performed; step four: whether the process of the speed increase is completed or not is judged, if the process of the speed increase is completed, a fuzzy PID control method is adopted to perform rolling line pressure dynamic regulation, otherwise, the step four is executed; and step five: whether a strip steel tail portion leaves an ultra fast cooling area is judged, if the strip steel tail portion leaves the ultra fast cooling area, the flow open-loop control is disconnected, the speed of the pump station is decreased to base speed, and a rolling line pressure dynamic regulation closed loop is disconnected, otherwise, the step five is executed.
